Kaspersky Security Network (KSN) is an infrastructure of cloud services providing access to the Kaspersky online knowledge base that contains information about the reputation of files, web resources, and software. Kaspersky Security Network is intended for improving detection of viruses and other threats, spam and phishing links, as well as for receiving statistics used to detect threats.

If you do not want to transmit data of your organization over the Internet, you can use the Kaspersky Private Security Network service.

Kaspersky Private Security Network (KPSN) is a solution that lets you receive access to Kaspersky Security Network data via a server located within your organization's network. KPSN enables Kaspersky applications to receive access to the online Kaspersky Knowledge Base for information about the reputation of files, web resources, and software. KPSN does not transmit statistics and files to Kaspersky. For more detailed information, please refer to the Kaspersky Private Security Network Administrator's Guide.

The Kaspersky Private Security Network service was designed for corporate customers who are unable to participate in Kaspersky Security Network for any of the following reasons:

• Servers have no Internet connection
• Legislative ban on transmitting any data outside of the country
• Corporate security requirements imposed on the transmission of any data outside of the corporate LAN

If this check box is selected, the application uses data from Kaspersky Security Network during a scan.

If this check box is cleared, Kaspersky Security Network is not used.

The check box is cleared by default.

The Use Kaspersky Security Network check box is available if the I accept the KSN Statement option is selected in the KSN Settings section in the Settings node. Use Kaspersky Security Network or the Use Kaspersky Private Security Network (KPSN) option. All settings of the Kaspersky Security Network service are applied to the Kaspersky Private Security Network service.

The maximum time of waiting for a response to a request of Kaspersky Security Network server (in seconds).

The default value is 5 sec.

This setting is available if the Use Kaspersky Security Network check box is selected.

Enables the scanning of archived files.

If the check box is selected, Anti-Virus scans archived files.

If the check box is cleared, Anti-Virus skips archived files without scanning them.

The check box is selected by default.

Enables / disables scanning of containers and multi-packed archives.

In the Scan attached containers/archives with nesting level not higher than spin box, you can specify the number of nested levels that the application must scan. For example, an email message contains an archive with 13 nesting levels. If the setting value is 10, Anti-Virus unpacks and scans the archive only down to and including the 10th nesting level. Files located at deeper nesting levels are not scanned. The maximum file value is 128. The default value is – 32.

If the check box is selected, Anti-Virus scans containers and archives according to the nesting level specified.

The value of the Scan attached containers/archives with nesting level not higher than setting covers attachment filtering. During attachment filtering, the application also unpacks and scans containers and archives according to the specified nesting level.

If this check box is cleared, Anti-Virus skips containers and archives without scanning them. During attachment filtering, the application scans containers and archives down to the second nesting level.

The check box is selected by default.

Excludes files from the scan by file names and file name masks.

If this check box is selected, the application skips files that match names and / or name masks in the list. You can create a list of file name masks.

The following buttons are used to create the list of file name masks:

• – adds the mask appearing in the entry field to the list of masks.
• – removes the selected mask from the list of masks.
• – exports the list of masks to a file.
• – imports the list of masks from a file.

If the check box is cleared, the entry field, buttons and list are unavailable, and mask-based exemption of files from scanning is not used.

The check box is cleared by default.

This setting is considered during attachment filtering. Files that have been excluded from Anti-Virus scanning by file names and/or file name masks will also be excluded from attachment filtering.

Excludes messages addressed to recipients in the list from scanning.

If the check box is selected, you can form a list of trusted recipients.

Recipients can be typed in the entry field or selected from Active Directory. To exclude messages for the Hub Transport role from Anti-Virus scanning, email addresses should be entered in the user@domain.com format. Names that are displayed have to be entered for the Mailbox role.

The following buttons are used to create the list of trusted recipients:

• – adds the record from the entry field to the list of trusted recipients.
• – removes the selected record from the list of trusted recipients.
• – exports the list of trusted recipients to file.
• – imports the list of trusted recipients from file.
• – adds an Active Directory account to the list of trusted recipients.

If the check box is cleared, the entry field, buttons and list are unavailable, and messages are not excluded from scanning based on their recipients.

The check box is cleared by default.
